App Router

The new App Router provides a more intuitive way to organize your application's routing structure:

  │   ├── page.tsx
  │   └── [slug]/
  │       └── page.tsx
  └── about/
      └── page.tsx

Server Actions

Server Actions allow you to run asynchronous code directly on the server:

"use server";

async function submitForm(formData: FormData) {
  const name = formData.get("name");
  // Process the form data
}
